Here in the good ol’ US of A, I once saw a woman lighting a cigarette for what appeared to be a 4ish toddler at a road side rest on the Ohio Turnpike. It made me feel sick, but then watching adults smoke does that, too. I should have called the police.

Michael Jackson dangled his toddler over a balcony, Steve Irwin (The Crocodile Hunter) dangled his toddler in front of Crocodiles during one of his shows.
The parent here may wish to consider the way karma dealt with those other cases.
